A simple bulb can result in a beautiful plant a few months later, and the foxtail lily is a very good reminder of this wonder of nature. From one spidery, woody tuber you can grow spires of densely packed flowers that can grow as tall as 6-feet tall. These fast growing plants are excellent cut flowers, also known as desert candles they grow on naked stems whose foliage starts to die out when the flowers form. The foxtail lilies need full sun with a rich well-draining soil and watering to keep the soil moist but not soggy at any time. Plant your foxtails in late winter or fall for late spring or summer blooms.
